COPD patients often have a wide range of physical (e.g., dyspnea, fatigue, pain) and psychological (e.g., depression, anxiety) symptoms and various other debilitating conditions that cause considerable suffering for the individual. Unfortunately, many of the symptoms and health problems in patients with COPD are unrecognized and untreated. Due to the irreversible nature of COPD, the aim is not to cure the disease, but to reduce symptoms and improve quality of life.
